Title: CUDA Benoit
Post by: RogerDahl on April 25, 2011, 06:42:23 AM
Hello everyone,

I'm looking for someone to test some software I have just finished:

http://www.dahlsys.com/software/benoit/index.html

"Realtime, high resolution, high iteration, supersampled, fractal zoom."

Requires a high end NVIDIA graphics card. So far, tested only on my
machine. Feedback is much appreciated :)

Roger

It says "Not a valid win32 application" :o :-\

No suprise it didin't render on my 68009800GT (oops), thats only v1.1 of CUDA IIRC. I guess you're using a later version for higher precision.

To be really useful for zoom movie creation you'd need to go deep & that means Arbitrary precision.
You may want to check out this arbitrary precision library, its for Linux but the code might be portable.

Thanks for trying to run the app! Are you on a 64 bit machine?

Thanks for the tip and for trying to run the app. This app wouldn't be able to generate fractal geometry in realtime with arbitrary precision, so, since the main point of this app is to create high quality fractal zooms without the traditional separate rendering step, we're stuck with fairly short zooms for now. At the normal speed, each zoom (track) runs for around 1 minute before the double precision resolution is exhausted. Since the app automatically strings together all the available tracks, and it comes with 22 tracks, there's around 22 minutes of fractal zooms to watch before it starts over :)

Reason: confusing my graphics card with my cell phone

Heh :) There is even a 6800GT card.

Probably it's too old, anyway it's weird that it says so :hmh:

Could be an issue with the app, though, if you have an older machine, it is unlikely to be 64 bit. Which version of Windows are you running and what type of processor do you have?
